Costello, who recently wrapped up his role as Chief Advocate at World Vision Australia, will take up a new post this month as Senior Fellow at CPX – a not-for-profit media company that seeks to promote public understanding of the Christian faith.

Simon Smart, executive director at CPX, says Costello is a “perfect fit” for the organisation.

“For better or worse, I find that I am a public Christian, and CPX is firmly in a zone where my heart is.” – Tim Costello

“Tim Costello, as an indefatigable advocate for those in need, embodies a version of Christianity that is deeply attractive, life-giving and broadly appealing,” Smart said in a statement.

“His passion to not only talk about faith but to live it out by speaking up for the voiceless, even at the risk of offending the powerful, has made him a popular figure in Australian public life.”

Costello will also continue as executive director of Micah Australia, a movement that seeks to raise a voice for victims of poverty and injustice. He’ll also continue in a range of volunteer positions which include Chair of the Community Council of Australia; founding board member and spokesperson for the Alliance for Gambling Reform; member of the SBS Community Advisory Committee; and patron of the National Youth Commission, and will even deliver a Masterclass at Hillsong Conference in Sydney next week.

In his new role with the Centre for Public Christianity, he will speak at CPX events, contribute to content through writing and the CPX podcast Life and Faith, and help build the organisation’s vision to raise up the next generation of public Christians.

He says offering a vision of the Christian faith that is all about Jesus’ message of radical love, grace and redemption “is something I can get excited about.”

“For better or worse, I find that I am a public Christian, and CPX is firmly in a zone where my heart is – engaging in productive conversations about what’s core to the Christian faith,” said Costello.

CPX is part of Bible Society Australia, which also publishes Eternity.
